The school is installing whiteboards in 5 classrooms. Whiteboards, including their
borders, are 6 feet wide by 10 feet long. The borders, which are 0.5 ft wide, will not be
varnished. The whiteboards can be varnished to resist stains for 40 cents per square
foot or can be varnished to avoid glare from ceiling lights for 25 cents per square foot.
If each room gets one whiteboard, how much more expensive will it be to varnish the
whiteboards for stains than to varnish them for glare?
